As conventional fossil fuel reserves shrink and the danger of climate change prevailing, the need for alternative energy sources is unparalleled. A smart approach to compensate the dependence on electricity generated by burning fossil fuels is through the power generation using grid connected PV system. Partial shading on PV array affects the quantity of the output power in photovoltaic (PV) systems. To extract maximum power from PV under variable irradiance, variable temperature and partial shading condition, various MPPT algorithms are used. Incremental conductance and fuzzy based MPPT techniques are used for maximum power extraction from PV array. Basically 11 kW Solar PV system comprising of PV array coupled with an Inverter through a dc-dc converter is considered for the analysis and output of the inverter is supplied to the load through the LCL filter. An Intelligent controller for maximum power point tracking of PV power is designed. Also, a fuzzy controller for VSC is developed to improve the system performance. The above proposed design has been simulated in the MATLAB/Simulink and analyzed the system performance under various operating conditions. Finally, the performance is evaluated with IEEE 1547 standard for showing the effectiveness of the system.

The overall performance of any solar energy project largely depends upon the available solar radiations, inclination and orientation of solar collectors. Presented in this paper is the analytical study on optimum tilt angles and lifetime differential savings for a distributed 200 kW grid connected mono-crystalline solar PV system operating at Khatkar Kalan, Punjab, India. The optimum tilt angles for monthly, seasonally and yearly basis is carried out by searching the values of tilt angle for which electric power output is maximum for a particular day or a specific period using energy conversion model. The results reveal that the yearly optimum tilt angle for the SPV plant at Khatkar Kalan is 36° which is 4.58° higher than the latitude angle. The power output from the array increases with increase in angle of tilt for winter months whereas the trend is reverse for the summer months. In winter months the maximum power output is achieved for the array surface with a tilt of angle 13° - 23° higher than the local latitude while for summer months the maximum power output is achieved at 16° lower than the latitude angle. The optimum tilt angles maximizing monthly power output for south facing surface shows that the monthly optimum tilt angle varies from 15° to 55°. Also the parametric analysis for some influential factors such as latitude of location and reflectivity of ground surface is explored.

This paper presents a thorough audit on various techniques of Photovoltaic (PV) framework under Partial Shading Conditions (PSC) which improves the yield voltage and power. Various productions report on PV with respect to control upgrades and its execution. In any case, perplexity emerges while choosing an approach that performs under every climatic circumstance. In this way, a fundamental audit of PSC systems is considered, which depends on most extreme power point following (MPPT) at Standard Test Conditions (STC). These MPPT strategies can follow the Global Peak (GP) at PSC. Broad research has been investigated in this field and numerous systems have been accounted for. In this paper, a point by point portrayal and order on various procedures of PV at PSC have been made as far as control factors, structure and hardware utilized in down to earth and business applications. Incomplete Shading is a significant test in photovoltaic (PV) frameworks which influences the quality and amount of the output power. The ordinary change of condition and the diminished profitability of PV Array is a significant obstruction in the brisk advancement of the sunlight based power age. A Solar PV system involves PV cluster connected with an Inverter through a dc-dc converter and the yield of the Inverter is associated with the heap. In any case, expansion to PV modules, and exhibit design, control electronic converters are in like manner fundamental parts for a sun oriented based power generation. It is basic to fathom the effect of fractional concealing to make compelling and strong Photovoltaic vitality transformation structure. PV exhibit course of action, converter arrangement and MPPT control strategy are the three basic districts where the vitality extraction from PV bunch can be improved under incomplete concealed condition. A point by point assessment study is coordinated among central and Micro-Inverter based PV systems and particular MPPT control techniques were pondered and considered under fractional concealed condition using MATLAB/Simulink.
